Presentation

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

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

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

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