[seqfan] A borderline case of "Is this sequence interesting?"

[Alonso Del Arte]

If we start Conway's PRIMEGAME with 3, we get

3, 165, 145, 385, 455, 85, 78, 66, 58, 154, 182, 34, 2, ...

Technically, this is not in the OEIS. But in a way, it is, as A007542, only
that the sequence is started at 2 rather than at 3. And there are other
values that will eventually lead to 3 (and then therefore 2 as well), so I
hesitate to even suggest modifying A007542. In fact, like Homer Simpson
bolting from the downhill car only to roll right back into the driver's
seat, powers of 2 with composite exponents eventually lead to powers of 2
with prime exponents.
