- Number of subwords UHH...HD in all peakless Motzkin paths of length n+3, where U=(1,1), D=(1,-1) and H=(1,0).at n=15A089742
- Numbers n such that 3*p(n)+2, 3*p(n+1)+2 and 3*p(n+2)+2 are consecutive primes in arithmetic progression 0,18,36 so p(n), p(n+1) and p(n+2) are in arithmetic progression 0,6,12.at n=10A102868
- Number of UH^jD's for some j>0, in all peakless Motzkin paths of length n (here U=(1,1), D=(1,-1) and H=(1,0); can be easily expressed using RNA secondary structure terminology).at n=18A187258
