[seqfan] Re: Is A290646 = A135517?

[Alonso Del Arte]

In trying to answer this question, I've come up with more questions and no
answers. What's another formula for A091090? I tried

binary weight(n XOR n + 1)

implemented in Mathematica with DigitCount and BitXor. This matches A1511
for the terms I've looked at, but I can't say for sure that this is indeed
a formula for A1511

 Perhaps with one judicious adjustment it's possible to turn A1511 into
A091090. Something like A001511[[n]] - Boole[IntegerQ[Log[2, n]]].
