Expansion of (1-x)/(1+x-x²+x³). A78042

a(n) = ∑_k=0..n T(n, k), array T as in A047080. A47081

Consider all quadruples {a,b,c,d} which reach {k,k,k,k} in n steps under map {a,b,c,d}->{|a-b|,|b-c|,|c-d|,|d-a|}; look at max{a,b,c,d}; sequence gives minimal value of this. A45794

Minimum value t such that all quadruples of Diffy_length >= n have a maximal value >= t. A65678

Tribonacci sequences A000073 and A001590 interleaved. A213816

Numbers of the form t_n or t_n + t_n+1 where {t_n} are the tribonacci numbers A000073. A308189

Expansion of -x²*(x⁹-x⁸+2·x⁷-x⁶+x⁵-2·x⁴+x²+1) / ((x⁶-x⁴+x²+1) * (x⁶+x⁴+x²-1)). A114952
