Acta Comment. Univ. Tartu. Math. 19, No. 2, 97-107 (2015).
Summary: Following a brief critique of the wording of Lewis Carroll’s {\it Alice’s adventures in wonderland}, this article offers some supplementary remarks relating to the solution of a $3\times 3$ pseudo-magic square problem posed by Lewis Carroll, a generalisation of the $3\times 3$ Lo-Su or luoshu magic square, the problem of installing $m^{2} = 25$ or $m^{2} = 36$ officers of $m$ different ranks and $m$ different regiments in a $m\times m$ Graeco-Latin square (with apposite remarks on the military career of Leonhard Euler’s third son and the recent coinage of the Empress Maria Theresa) and a list of fourteen portraits of mathematicians on banknotes paying particular attention to those of Sir Isaac Newton and Florence Nightingale.
