A177800 The maximal length of the chain of consecutive primes starting with A177798(n) such that all of them are odious. 2

COMMENTS

In contrast to sequence of all positive integers, where the length of a chain of consecutive odious numbers cannot exceed 2, we conjecture that over primes the length is not bounded.
