Presentation

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

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

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