Walter Trump
Walter Trump is a German mathematician. He is known for his work in recreational mathematics.
He has made contributions working on both the square packing problem and the magic tile problem. In 1979 he discovered the optimal known packing of 11 equal squares in a larger square,[1] and in 2003, along with , developed the first known magic cube of order 5.[2] In 2012, Trump et al. described a model for retention of liquid on random surfaces.[3] In 2014, he and were able to calculate all 8x8 bimagic squares.[4]
Until he retired in 2016, Trump worked as a teacher for mathematics and physics at the Gymnasium in Stein, Bavaria.
