A271979 - Goodstein function

Example

Some sequences - mainly those with the keyword base - have terms with interesting digit patterns. Please look at these examples.

Such a visualization may be used for pattern analysis as well as for presentation.

Implementation

I wrote a Perl script which

  • fetches a b-file from the OEIS or reads it from the local disk,
  • uses CSS to colorize every digit in the a(n) terms,
  • outputs a corresponding HTML file.

Questions

  • The individual colors are a matter of taste of course. Should the palette for the digits be modifiable by the user?
  • Is it sufficient to use the script offline, or should it be callable by a web form?
