[seqfan] Re: possible sequence

[Hans Havermann]

Charles Greathouse:

2: 2^86 (26 digits)
3: 2^184 * 3^88 (98 digits)
5: 2^184 * 3^88 (98 digits)
7: 2^25 * 3^227 * 7^28 (140 digits)

"One problem is that this sequence grows very quickly."

It didn't grow at all from 3 to 5. What grows is the number of combinations of multipliers but I'm not at all sure that this translates into anything more than this initial exuberance. Might there not be a size limit after which it will be difficult to achieve anything more than incremental advances?
