Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 28 points:

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