Presentation

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

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

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