Presentation

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

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

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