Arrange N into a two-dimensional array

[QUOTE="andrewkirk, post: 5548241, member: 265790"] Your approach is a little confusing. You use the symbol ##A_j## but do not say what it is. You then set out to define a function but the bidirectional arrow ##\leftrightarrow## leaves us wondering which way the function goes, and it does not tell us what the domain and range are. We can say nothing about whether a function is bijective unless we know its domain and range. The classical, and clearest, way to define a function ##f## is to write something like: [INDENT]'define the function ##f:D\to R## such that ##f(x)=##<formula specifying the result of applying the function to ##x##>'[/INDENT] This tells us that ##f, D## and ##R## are the function's name, domain and range respectively, and the 'such that' part then tells us what value is obtained by applying it to an arbitrary element of the domain.
