Systematic Studies in Pattern Avoidance

Maple Packages:

• FINLABEL (by Vince Vatter) -- finds generating functions and more for the number of permutations avoiding certain sets of patterns
• WILFPLUS (by Vince Vatter) -- finds recursive schemes to count permutations avoiding sets of patterns
• WILF (by Doron Zeilberger) -- another package to study permutations avoiding sets of patterns
• GuessHolo (by Doron Zeilberger) -- computes recursive formulas for sequences of numbers and performs various asymptotic tests
• WILFBOOK (by Lara Pudwell) -- systematically tests what can be counted by FINLABEL and WILF for specified pattern sets and summarizes results
  (NOTE: to run WILFBOOK, you must first load WILF and FINLABEL into your maple session, and the proceed with WILFBOOK))
