A083786: Composite numbers mod 10. 4,6,8,9,0,2,4,5,6,8,...
A088308: Composite numbers mod 10. 2,4,6,8,9,0,2,4,5,6,8,...
(both contributed by the same person, within less than three months)

After omitting the wrong initial term 2 in A088308 this is the same as A083786. Therefore A088308 should be deleted.

Isn't it a shame that this has not been detected for more than two years? And doesn't it demonstrate the sloppiness of the submitter?
