Decomposition of A090050
Numbers having equal length of longest contiguous block of zeros and ones in binary expansion.
Decomposition of Symmetric primes
Symmetric primes: an odd prime p is symmetric if there exists an odd prime q such that |p-q|=gcd(p-1,q-1).
Decomposition of Asymmetric primes
Asymmetric primes: an odd prime p is asymmetric if there is no odd prime q such that |p-q|=gcd(p-1,q-1).
Decomposition of A090403
Balanced primes: Primes which are both the arithmetic mean and median of a sequence of 2k+1 consecutive primes, for some k>0.
