COMMENTS

Analog of A249482 in Fermi-Dirac arithmetic, based on distinct terms of A050376 as "primes". Surprisingly there is a giant contrast between this sequence and A249482.

For k >= 1,

in interval [a(2k-1), a(2k)], L(n) <= 0,

in interval [a(2k), a(2k+1)], L(n) >= 0.

In particular, for k=1, in interval [2, 34], L(n) <= 0.
