Hence 3 = 11_2 = A066044(2) is not Brazilian and therefore not highly Brazilian. However, except for 3, the sequences A066044 and this one are the same. %C A329383 The first time the name "highly Brazilian number" was used is in Daniel Lignon's book in reference. - _Bernard Schott_, Jul 27 2020 %D A329383 D.
