What Does Summation Mean? Carl Friedrich Gauss, one of the greatest mathematicians who ever lived, was given the following problem to solve as an elementary school student in the late 18th century: What is the sum of the integers from 1 to 100? To his teacher's surprise, Gauss provided ...

then the back face then the left face. This four-move sequence still takes 1,260 twists to solve itself, but that’s now ‘just’ 315 repeats of the sequence. (A technicality within a technicality: if I’m counting rotating the whole cube as a single move, do I count a solved but ...
(That inappropriate "sigma" notation had me confused at first.) However, the limits of the summation in your H(f)H(f) equation should be n = 0 to n = (41-3)/2 = 19. (Was that H(f)H(f) equation in the Symposium paper? I hope not.) Your second question puzzles me. If ...
Or, it can be more simply represented by the followingsummation notation: Numeric Sequence in Computational Logic Computational logic uses computers to establish facts in a logical formalism [2]. The facts are defined much more precisely than simple “a sequence of ordered numbers”: ...
