This is a semi-generic approach to generating sequences of numbers in Perl by an iterator, and for some sequences by "ith" or predicate too.

Download version 75 here, either the full source here or from CPAN, or a Debian package here or from my repo.

Math-NumSeq-75.tar.gz (867k, and sig)
libmath-numseq-perl_75-0.1_all.deb (511k, and sig)

And some separate "alphabetical" related sequences, using the "Lingua" modules. Download from CPAN, or here.

Math-NumSeq-Alpha-4.tar.gz (60k, and sig)
libmath-numseq-alpha-perl_4-0.1_all.deb (17k, and sig)

The sig files are Gnu PG ascii armoured signatures generated from my key. There's a SIGNATURE file inside the .tar.gz for cpansign too. Older sources can be found at backpan.

Math-PlanePath includes some NumSeq tie-ins to present coordinates and turns as sequences.
