Thornal
Thornal is a special instance of a base-32 numeral system created for legibility. It is one of three numeral bases—the others being dwarf thornal and base 64—that lie outside the alphanumeric natural base set, of which binary, octal, decimal, and hexadecimal are members. It was created as a binary-friendly number base with improved legibility by removal of the characters 0, 1, I and O.
History
The term thornal was originally coined by Scottish programmer Jamie Christie, according to his contemporary Alexander[1] some time around 2015. It is not known for certain whether Jambo's version of thornal meant any particular version of base-32, but since no one else was using the term, Alexander decided it would be useful to distinguish this special legible version of base-32 from the base-32 present in the alphanumeric natural base set, and any other version of base-32 that may be floating around on the Web.
