30-40M and 40-50M took 8 and 9.5 hours respectively. It has also grown considerably in size. at 50 M it was 7809 digits in size, with a 8307 digit maximum in the 10M before. For a sequence that...

I understood the intention haha, the naughtier version did briefly come to mind though :P (I am from the UK)
Today I've started to try to resolve 22246 in chunks of 10M steps (takes about 3 hours...

Honestly, I'm a little surprised that the result of the operation is on average 0.75 the size of the input. I'd have thought it would be a bit narrower than that, especially considering the size of...

The likelihood of a random number containing a 0...

The likelihood of a random number containing a 0 increases as the size of the integer increases, so there will be a certain range of values at which numbers no longer increase on average. This is the...

After some more calculations, it seems that I overlooked something: negative integer powers can be to to create integers of seemingly arbitrary length. Case in point: 260*32

I have been subscribed to Numberphile for several years, I do enjoy their content, especially some of the more esoteric stuff. As for the Collatz Conjecture itself, the answer is very likely yes...

Raising groups of digits to powers, equalling itself

My first attempt at sharing some recreational mathematics seems to have backfired somewhat, being accused of not being "maths". Maybe this will do better, in a recommended subforum?

I couldn't...

I had already read the Quanta article, and am very familiar with OEIS. I have read quite a bit about the collatz conjecture in fact, and have done so for 10+ years since learning it as a kid. I'm not...

I wouldn't call it numerology, at least in the dictionary definition of the word. This to me is purely recreational mathematics. I think it is a bit unfair to suggest it isn't mathematics, though I'm...

Binary Complement Sequences and 22246

First post here, hopefully in the right place, I did look around a bit.

I have an interest in exceptions, outliers and holdouts. As an example, I have more interest in 27 having an unusually long...
