Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 63

A minimal faithful permutation representation — 3 generators on 23 points:

(2,5,6)(4,8,9)(10,14,16,12,15,11,13)(17,18,19,20,21,23,22);(11,12,13)(14,16,15)(18,19,21)(20,22,23);(1,2,4)(3,6,8)(5,9,7)(18,19,21)(20,22,23)

Polycyclic presentation:

3^4,7^2|c^a=cd,e^a=e^2,e^b=e^2,f^a=e^2f,f^b=f^2
