greekctr – Rep­re­sent coun­ters by let­ters of the Greek al­pha­bet

The com­mands \greek and \Greek use (math­e­mat­i­cal) Greek let­ters (or up­per case Latin let­ters, where ap­pro­pri­ate), to enu­mer­ate num­bers up to 24. Num­bers 25 and above are rep­re­sented with \omega/\Omega, and pro­voke an er­ror mes­sage.
The pack­age is part of Jörg Knap­pen’s col­lec­tion.
