Dear Sequence Fans,
in my "coincidences" scans I just stumbled over the
A001651 Numbers not divisible by 3.
%K nonn,easy %O 1,2 %A N. J. A. Sloane
A133223 A007605 [Sum of digits of n-th prime],
sorted and duplicates removed. ...
%K nonn,base %O 1,1 %A Lekraj Beedassy, Dec 19 2007
%C Presumably this is 3 together with numbers
greater than 1 and not divisible by 3.

This is rather astonishing to me. Has it been proven
in the meantime? Is it contained in the paper of
Mauduit and Rivat?
Best regards - Georg
