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

If anyone is interested, I have a list of the Ulam(1,2) numbers <= 5,000,000 and I expect to have one for <= 10,000,000 tomorrow. If you want me to send you a copy, let me know. The former is over 3MB, storing the numbers in an ASCII text file. It is 900KB zipped, or 1.5MB stored as 32-bit (binary) integers.
