RE: HITTING TWO TARGETS: OO + MATH TOPIC

Note: this had some terminological problems i.e. no such thing as a 'relative prime', only integers 'relatively prime' to others. Plus there's no need to stipulate the modulus be a prime -- in fact one of my examples on math-learn used a modulus of 20. Thanks to David Ullrich on sci.math for these tips, plus urging me to promote Group to a superclass so that we might subclass _specific_ kinds of group, like these groups of coprimes, as subclasses thereof. I have since incorporated these suggestions into my draft code, with an eye to doing another web essay later. Kirby
