Presentation

minimal degreeμ(G) = 39
transitive degreeμt(G) = 896

A minimal faithful permutation representation — 4 generators on 39 points:

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