Presentation

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

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

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