Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 336

A minimal faithful permutation representation — 3 generators on 26 points:

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