libalgorithm-combinatorics-perl binary package in Ubuntu Xenial arm64

 Algorithm::Combinatorics is an efficient generator of combinatorial sequences.
 Algorithms are selected from the literature (work in progress). Iterators do
 not use recursion, nor stacks, and are written in C. See Math::Combinatorics
 for a pure-Perl module with similar (if less efficient) features.
