Multimagic square 36, 100, ... Value for Trimagic squares 1, 50, 675, 4624, ... Similarly the tetramagic sequence 4-Power 0, 1, 16, 81, 256, 625, 1296, ... Sum of 4-Power 0, 1, 17, 98, 354, 979, 2275, ... Sums for Tetramagic squares 0, 1, 177, ... The first known bimagic square has order 8 and magic constant 260 and a bimagic constant of 11180. It has been conjectured by Bensen and Jacoby that no nontrivial bimagic squares of order less than 8 exist. This was shown for magic squares containing the elements 1 to "n" by Boyer and Trump. However, J. R.
FS Class 625 with the Franco-Crosti boiler (with two pre-heaters placed on the sides of the boiler), these engines were visually distinctive. The design was not successful, and these engines were all withdrawn by the early 1970s, with none surviving into preservation. A number of scale models of class 625 locomotives have been manufactured by Italian model company Rivarossi. Locomotive 625 116 featured in the 2013 Italian cinema film "The Magistrate" by Giulio Base. Locomotive 625 017 has gained some attention through operations on the Vatican Railway (the world's only national railway network to own no locomotives). The engine hauled a train for
