Presentation

minimal degreeμ(G) = 38
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 38 points:

(1,2);(7,8)(9,15)(10,25)(11,17)(12,18)(13,19)(14,20)(16,24)(21,29)(22,30)(23,31)(26,34)(27,35)(28,36)(32,38)(33,37);(3,4)(5,6)(7,9)(8,15)(10,12)(11,21)(13,24)(14,22)(16,19)(17,29)(18,25)(20,30)(23,27)(26,38)(28,37)(31,35)(32,34)(33,36);(9,21,22,37)(10,23,24,38)(11,26)(12,13)(15,29,30,33)(16,32,25,31)(17,34)(18,19)(27,28)(35,36);(4,6)(7,10,12,22,14,24,13,9)(8,16,18,15,20,25,19,30)(11,23,26,21,28,38,27,37)(17,32,34,33,36,31,35,29)

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
