  1. It is about multiplicative persistence which means roughly the following. We take an integer and multiply the digits together to get a new number. This will be done in a loop until we get a single digit number. Example: 3279->378->168->48->32->6. The persistence of 3279 is 5 as it takes 5 steps
  2. TL;DW: Multiplicative persistence is simply the count of iterations when multiplying the digits of a number and its persistent results until you are left with a single digit. Example: The number 796 has a Multiplicative Persistence of 5: 7 x 9 x 6 = 378. 3 x 7 x 8 = 168. 1 x 6 x 8 = 48. 4 x 8 = 32. 3 x 2 = 6
  3. Multiplicative persistence. The number of iterations needed for () to reach a fixed point is the multiplicative persistence of . The multiplicative persistence is undefined if it never reaches a fixed point. In base 10, it is conjectured that there is no number with a.

Probably finite. The persistence of a number (A031346) is the number of times you need to multiply the digits together before reaching a single digit. From David A. Corneth, Sep 23 2016: (Start) For n > 1, the digit 0 doesn't occur. Therefore the digit 1 doesn't occur and all terms have digits in nondecreasing order GitHub is where people build software.

Instantly share code, notes, and snippets. giuliano0 / mult_persistence.py. Created Mar 28, 201 Base 7 reaches a maximum multiplicative persistence of 8 when there are 9 of at least one repeated digit, and it stays there until 39 of one digit, at which point it starts to taper off. I've only been able to test through 115 of any digit so far, and it's down to a consistent maximum multiplicative persistence of 3, I fully expect it will reach 2 eventually and stay there, possibly permanently As with many sequences, multiplicative persistence (MP) is perhaps best explained by example, not jargon. The MP of 35 is 1 because: consider watching this video from Numberphile. Regardless, the record has held for decades and no one has been able to expand the series. By my calculations, it's effectively impossible. The Algorithm . We've have been looking at MP in the wrong direction.

  1. Numberphile multiplicative persistence. Multiplicative Persistence (extra footage) - Numberphile, In mathematics, the persistence of a number is the number of times one must apply a given operation to an integer before reaching a fixed point at which the operation no longer alters the number. Usually, this involves additive or multiplicative persistence of an integer, Numberphile on YouTube (Mar 21, 2019). Retrieved Multiplicative Persistence. Multiply all the digits in a number; Repeat.

  1. Over at NumberPhile, Matt and Brady are talking about multiplicative persistance:. Take a number. Multiply all its digits together. Repeat with the new number until it reaches a single digit. For instance, starting from 327, the product of the digits 3, 2 and 7 is 42, then recurring with 42 the product of the digits 4 and 2 is 8, which is the final answer; we say the sequence 327 → 42 → 8.

  1. For context, this code is written on a video within the channel Numberphile by Matt Parker talking about multiplication persistence. The code is written in Python 2, and my question is about the line return DONE. Evidently, this prevents an infinite loop from being generated, as it is clear running an example (below) with and without that line: def per(n, steps = 0): if len(str(n)) == 1.

The Numberphile video talks about the curious arithmetic you get when you do the abelian sandpile model on a square board. Garcia-Puente focusses on a 3-by-3 square. It's natural to generalize from squares to rectangles, and then to specialize from rectangles-in-general to rectangles of height 1. In particular, if the board is 1 by 9, then the sandpile group is just modular arithmetic with. But her persistence was more than awesome. According to researchers who look at how people think of themselves as learners (Carol Dweck is one), it is exactly this kind of persistence, a belief that a person isn't stuck in his or her knowledge state (e.g. smart or dumb) but that we are malleable--our intelligence is malleable and can be improved by hard work. Summer is just that kind of. Lacunacrity and Persistence do not need to be exactly in the power of 2, although it is quite common to do so. Figure 5: Combined Perlin Wavelength.

A second consequence of finite thickness is a non-zero weight: a strip held horizontally in a gravitational field also deforms longitudinally (i.e., in the direction orthogonal to the imposed transversal curvature) to release.
