Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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