Presentation

minimal degree	μ(G) = 48
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 3 generators on 48 points:

(1,2,4,8,5,9,12,15,6,3,7,10,13,11,14,16)(17,18)(19,27)(20,31)(21,36)(22,24)(23,28)(25,34)(26,33)(29,47)(30,44)(32,42)(35,43)(37,41)(38,46)(39,48)(40,45);(17,19,22,30)(18,23,24,38)(20,32,35,48)(21,37,33,29)(25,41,40,47)(26,42,36,39)(27,43,44,31)(28,45,46,34);(1,3,4,10,5,11,12,16,6,2,7,8,13,9,14,15)(18,24)(23,38)(25,40)(26,36)(27,44)(31,43)(39,42)(41,47)
