[юрий герасимов]

If 
A156695 ---> odd numbers which are not of the form p + 2^a + 2^b, a, b > o, p prime ---> 1, 3, 5, 6495105,...
then 
A______? ---> numbers which are not of the form 2^x + p*2^y, x, y >=0 and p prime ----> 1, 2, 127, a(4)?, a(5)?, a(6)?

Cf. A______? --->number of distinct primes p such that n = 2^x + p*2^y has a solution with x, y >= 0 and p prime ---->

0, 0, 1, 2, 2, 2, 2, 3, 3, 2, 3, 3, 3, 3, 4, 3, 2, 4, 3, 3, 4, 3, 3, 4, 3, 3, 4, 3, 2, 4, 2, 4, 4, 2, 4, 4, 2, 4, 5, 3, 2, 5, 2, 4, 6, 3, 
3, 5, 4, 2, 3, 3, 2, 5, 3, 2, 3, 2, 2, 5, 3, 3, 5, 4, 2, 4, 2, 4, 6, 4, 2, 5, 2, 3, 7, 4, 4, 5, 2, 4, 4, 2, 4, 6, 2, 2, 6, 4, 2, 7, 3, 3,
4, 3, 3, 3, 2, 5, 3, 3, 2, 4, 2, 4, 7, 2, 3, 6, 2, 4, 5, 4, 3, 4, 3, 2, 5, 2, 2, 5, 2, 3, 3, 3, 3, 4, 0, 5, 4, 2, 3, 4, 3, 2, 6, 3, 2, 7,

I want to know the option of the causes these sequence that is not at present in the OEIS. 
I need help in their software testing and related supplements. 
Tranks in advance for your efforts.
