a(n) < A086958(n) < A086959(n), A086956(a(n))=A086956(A086958(n))=A086956(A086959(n));

n and A086956(n) are divisors of a(n);

A086960(a(n)) = A086958(n), A086960(A086959(n)) = a(n);

A086961(a(n)) = A086959(n), A086961(A086958(n)) = a(n);

A086962(a(n)) = a(n);

A086963(a(n)) = A086959(n), A086963(A086959(n)) = a(n);

A086964(a(n)) = A086958(n), A086964(A086958(n)) = a(n).
