avoidsPatterns -- whether a permutation simultaneously avoids a list of patterns

• Usage:

  avoidsPatterns(w, patterns)

• Inputs:
  • w, a permutation,
  • patterns, a list,
• Outputs:
  • a Boolean value,

i1 : p = permutation {3,1,2,5,4}

o1 = Permutation{3, 1, 2, 5, 4}

o1 : Permutation

i2 : avoidsPatterns(p, {{2,1,4,3}, {1,4,3,2}})

o2 = false
