Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 320

A minimal faithful permutation representation — 3 generators on 21 points:

(1,2,4,5,3)(7,11)(10,12)(14,15,16,18,17,19,20,21);(6,8,9,13)(7,10,11,12);(2,3)(4,5)(6,7,9,11)(8,12,13,10)(15,18)(16,20)(19,21)

Polycyclic presentation:

2^6,5|a^2=e,b^2=e,c^2=de,d^2=f,b^a=be,c^a=cd,d^a=df,g^a=g^4
