title: 'magicrect: Construct Magic Rectangles and Nearly Magic Rectangles'
version: 1.0.0
abstract: Constructs a magic rectangle or a nearly magic rectangle of order p x q
  for every order for which one exists, together with existence classification and
  verification utilities. A magic rectangle arranges the integers 1 to p*q so that
  all row sums are equal and all column sums are equal; it exists exactly when p and
  q have the same parity, excluding 2 x 2 and degenerate single-row/column cases (Hagedorn,
  1999, <https://doi.org/10.1016/S0012-365X(99)00041-2>). When p and q have opposite
  parity a nearly magic rectangle exists instead, with constant sums along one direction
  and sums differing by at most one along the other (Chai, Singh and Stufken, 2019,
  Journal of Combinatorial Designs 27(6), 368-376). Implements the constructions of
  De Los Reyes, Das, Midha and Vellaisamy (2009) for even by even orders, Chai, Das
  and Midha (2013) for odd by odd orders, and Chai, Singh and Stufken (2019) for the
  nearly magic (even by odd) case.
