Presentation

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

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

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

Polycyclic presentation:

2^6,5|a^2=e,b^2=d,c^2=d,e^2=f,c^a=cef,g^a=g^4,c^b=cd,e^c=ef
