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