     “According to permutation the forty-two individual faculties of genetic instincts of which the human mind is composed may combine in 2,810,012,235,505,759,797,086,285,212,489,023,129,768,000,000,000 different ways.” Think of it!

     The universe, having run down, will be obliged to commence a new cycle of stellar evolution, and in the fullness of time the exact state of affairs existing in the year of grace 1940 will repeat itself. When will this be? The English scientist, [J. B. S.] Haldane, has worked it out. It will fall due in or about the year, ten to the ten-to-the-hundredth power. TAKE ten, raise it to the hundredth power by adding 100 noughts. The serpentine figure resulting is known, technically, as a thousand sedecillions. […] FOR our “Golden Agers” the result may be discouraging, although what different it will make to us whether the Golden Age takes a million, or a billion, or a sedecillion years to return, is not very obvious.

     A British cryptic has 15 squares in each row and column. That gives 53,919,893,334,301,279,589,334,030,174,039,261,347,274,288,845,081,144,962,207,220,498,432 ways of arranging those 225 black and white cells – but very few of them would make a decent puzzle, or have a pleasing look. With a quick crossword, it’s thirteen, which is still knocking on for seven and a half sedecillion combinations.
