Re: [math-fun] Ulam(1,2)

I'm getting in on this in the middle, so I don't know what you're discussing, but maybe I could see what I get with my program.

Thanks for the offer. There are two things I want verified. First, is it true that: u(1000)=12336 u(1091)=13533 u(1210)=14894 u(1730)=21870 u(1748)=22151 u(1947)=24851 u(1999)=25511 ? This is with zero-based indexing (u(0)=1, u(1)=2, u(2)=3, ...), so maybe you need to add 1 to the indices. Second, letting f(n) = (u(n)/21.6) - floor(u(n)/21.6, for what n in 1000...1999 is .5 <= f(n) < .55? Thanks. Dan Hoey
