a(n)=i => i is the smallest index such that A088568(i)=n. Because the difference between successive elements of A088568 can only be -1 or 1, the sequence is monotonic increasing except for a(1) < a(0). - Paolo Bonzini, Jul 06 2016

			 A088568 begins with 1,0,1,2.. 0 appears first at index 2, 1 appears first at index 1, 2 appears first at index 4. - _Paolo Bonzini_, Jul 06 2016
