Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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