Presentation

minimal degreeμ(G) = 36
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 36 points:

(1,2)(3,4)(13,14,16,18)(15,19,20,17)(21,22)(23,26)(24,25)(27,28)(31,35)(34,36);(1,2,3,4)(7,11)(10,12)(22,24)(26,28)(29,30)(31,34)(32,33)(35,36);(6,9)(7,11)(15,20)(17,19)(30,33)(34,36);(1,2,3,4)(5,6)(7,12)(8,9)(10,11)(13,14)(15,17)(16,18)(19,20)(21,23)(22,26)(24,28)(25,27)(29,30)(31,34)(32,33)(35,36);(1,2)(3,4)(5,7,8,11)(6,10,9,12)(13,15,16,20)(14,17,18,19)(21,24,25,22)(23,26,27,28)(29,31,32,35)(30,34,33,36)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
