This statement was interesting to me because the super flip is the example of a proven 20 HTM case, so I'm going to guess this 26 QTM case is also solvable in 20 HTM?

Superflip is only one of at least 1,445,274 proven 20f* positions.

Edit: OK, I think that superflip may have a direct mathematical proof of being 20f* while other 20f* positions have probably only been "proven" so by use of computer analysis.

You happen to be correct that the 26q* position is also one of the known 20f* positions. From Reid's web site, it can be created by:

U2 D2 L F2 U' D R2 B U' D' R L F2 R U D' R' L U F' B' (26q*, 21f)

F U2 R L D F2 U R2 D F2 D F' B' U2 L F2 R2 B2 U' D (20f*, 28q)
