OEIS Sequences

Number of integer partitions of n that cannot be partitioned into constant multisets with distinct block-sums. A381717
Factorial splitting: write n! = x·y*z with x<y<z and·maximal and z is minimal; sequence gives value of z-x. A61033
Least number with exactly n prime factors counted with multiplicity which gives a different number with exactly n prime factors counted with multiplicity when digits are reversed. A109018
Numbers that have exactly eight prime factors counted with multiplicity (A046310) whose digit reversal is different and also has 8 prime factors (with multiplicity). A109028
T(n,k)=Number of (n+2)X(k+2) 0..1 arrays with no 3x3 subblock diagonal sum 3 and no antidiagonal sum 3 and no row sum 0 and no column sum 0. A256748
Product of the nonzero exponents in the prime factorization of n!. A135291
a(n) is the smallest integer k such that the Diophantine equation x3 + y3 + z3 = k3, where 0 < x <= y <= z has exactly n integer solutions. A377444
Numbers k such that σ(k) AND 3·k = 3·k, where AND is bitwise-and, A004198. A388022
Total number of parts coprime to n in the partitions of n into 8 parts. A363326
Sum of all the parts in the partitions of n into 5 squarefree parts. A308839
