The quite uninteresting number 8795 is already in the sequence
A000027 The natural numbers.
A001477 The nonnegative integers.
A002262 Integers 0 to n followed by integers 0 to n+1 etc.
A004086 Read n backwards (referred to as R(n) in many sequences).
A005408 The odd numbers: a(n) = 2n+1.
A006257 Josephus problem: a(2n) = 2a(n)-1, a(2n+1) = 2a(n)+1. (I think)
A008587 Multiples of 5.
A008706 Coordination sequence for 3.3.3.4.4. planar net.
...
A020652 Numerators in canonical bijection from positive integers to
positive rationals.
A038566 Numerators in canonical bijection from positive integers to
positive rationals <= 1
A049653 2*n-prevprime(2*n). (I think)
...
and many others. No need to construct artificially particularly weird
(or even "base") sequences to include it. It would also be:
the 5th in the sequence
Azzz : positive multiples of 1759,
the 3rd in the sequence
Ayyy : odd multiples of 1759,
and the first in the sequence
Axxx : common multiples of 5 and 1759
(= multiples of 1759 ending in 5, but this is "base" and thus prohibited).
No need to say why 1759 is special : in about 200 OEIS sequences its
among the first 30 terms or so.
