Bruno Berselli: Vincenzo: tra la tua proposta (#3) e l'attuale forma della voce c'è un evidente abisso! Ho cercato di dare contenuti e sostanza a questa sequenza, ciò a cui avresti dovuto provvedere tu prima di presentarla. Capisco le tue difficoltà, tuttavia OEIS non incoraggia gli autori a presentare i propri contributi appena imbastiti, bisogna innanzitutto capire quello che si propone e spiegarlo con chiarezza agli editori. Produrre una sequenza non è un atto meccanico, ma un importante e prezioso lavoro intellettuale che deve essere condotto con vera passione e accuratezza, responsabilmente, non "come capita". Se tale lavoro risulta incomprensibile o insostenibile, è meglio non affrontarlo --- Grazie della collaborazione.
