2611 terminates, n=67, P123.

Right now, the lowest composites of all open HP10 in the FactoringDatabase are C101.

I've done all the base 2 home prime "pi sequences" up to [URL="http://www.factordb.com/search.php?se=2&aq=3141592653&action=last20&fr=&to="]3141592653[/URL].

Interestingly enough, all the base 2 "pi sequences" below 3141592653 are terminated, and as such it is the lowest such open-ended sequence.

I won't be continuing with 3141592653, so if some enterprising invididual out there has the resources to take on a C90 sequence, have at it! :smile:

If it's a base 2 pi sequence, shouldn't it be [URL="http://www.wolframalpha.com/input/?i=pi%20in%20base%202"]11.001001000011...[/URL][FONT=monospace]? :smile:

LOL--er, correction, the HP[sub]2[/sub] "pi sequences". :smile:

Or to be slightly and uselessly more precise: the HP[sub]2[/sub] pi[sub]10[/sub] sequences.

11275 terminates, n=46, P90.

7248 terminates, n=59, P121.

2048 terminates, n=52, P111.

After 2[sup]11[/sup], now 3[sup]12[/sup]=531441 terminates, n=51, P112.

Right now, the lowest composites of all open HP10 in the FactoringDatabase are C103.
