Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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