%N Index of the smallest prime where n consecutive leading binary digits of the index match n consecutive leading binary digits in the prime.
%C Similar to A133583, except the comparison is done in binary.
%e a(4) = 25 since 25 in binary is 11001, the 25th prime is 97, or 1100001 in binary and the first 4 digits of these two binary numbers coincide.
%Y Cf. A245521, A245522, A245523, A133583, A133584, A133589, A133590.
