%N Starting values of runs of consecutive numbers in A367090, i.e., minima of gaps in the set of sums of distinct powers of 3 and distinct powers of 4.
%C Also: terms a(n) of A367090 such that a(n)-1 is not in A367090.
%C ("Consecutive" includes the possibility of having a gap of just one single isolated missing number.)
%C This sequence together with A367091 (run lengths), provide a "compressed version" of A367090.

%e Sequence A367090 (= numbers that are not the sum of distinct powers of 3 or 4) starts (62, 63, 143, 144, 207, 208, 209, 210, ...), so the first three runs of consecutive terms start at a(1) = 62, a(2) = 143, and a(3) = 207.
