Otter and Mace Users
This page contains some of the researchers
and educators who have used the automated deduction systems
Otter or Mace.
Maybe this list should be separated into several areas:
 research in mathematics and logic
 other applications
 Otter or Mace as an automatic subsystem
 evaluation of other systems
 education
Let us know if we should add, change, or remove entries.
Note: the secondary points are contexts in which
Otter or Mace were used, and not necessaily
the primary research areas of the users.
