1729/1728: Difference between revisions

The name ''ramanujanisma'' was first proposed by [[User:Fredg999|Frédéric Gagné]] in reference to the anecdotal story of [[Wikipedia: Ramanujan|Srinivasa Ramanujan]] finding 1729 an interesting number<ref>Before Srinivasa Ramanujan had died of amoebic dysentery in 1920, the year prior in 1919 fellow mathematician and Ramanujan's own mentor [[wikipedia:G._H._Hardy|G. H. Hardy]] had visited him while he lay ill in Putney, London, UK. The number of the taxicab he had ridden was 1729 and Hardy would then hope its perceived dullness was not a bad omen, to that of which Ramanujan stated this fact.</ref>. This comes from its property of being the second of ''n'' 'taxicab' numbers whose cubic sum not only is restricted to two components but also to ''n'' equivalencies (the first is two and the third is 87539319). Alternative names include ''lesser massma'', proposed by [[User:Eliora|Eliora]], in reference to the number 1728 being known as the ''Maß'' in German (although this is actually an urban legend as 1728 shares in common the expression great gross with English, and is thus called ''großes Gros''), and ''dodecentisma'', proposed by [[User:Godtone|Godtone]], in reference to the size being close to the relative ''cent'' of ''12''edo (''dodeca'') (12 × 100 = 1200 and this comma is a low [[prime limit]] superparticular approximating 1/1200 of an octave) and in reference to 1728 being a power of 12 (''dodeca'').
