> For the values of m=8,13,19,26,34,43,46,68, none of which is equal to 2P(n) or 2P(n)+1 for some integer n, there are repeated values greater than 1 in T_m:
Note that for m = 11, 14, and 60, there are two pairs of repeated values. Perhaps only one of these pairs meets your 2P/2P+1 exclusion principle?

Blindly using the second (of three) Mathematica formulation in A008284, I'd guess (based on a half-day run) that it would take me about three days.
