Dear seqfans,

there's an old sequence of David Wilson's that needs a few more
terms - any volunteers?

%I A020753
%S A020753 1,2,3,4,5,6,7,8,9,10,12
%N A020753 Sizes of successive increasing gaps between square-free numbers.
%K A020753 nonn,more
%O A020753 1,2
%A A020753 dww
%Y A020753 Cf. A020754, A020755.

The two related sequences are

%I A020754
%S A020754 1,3,7,47,241,843,22019,217069,1092746,8870023,221167421
%N A020754 Increasing gaps between square-free numbers (lower end).
%K A020754 nonn
%O A020754 1,2
