List of decimal digits, alphabetically sorted by their names in Norwegian resp. Swedish: 8 _ åtte _ åtta, 1 _ en/ett _ en/ett, 5 _ fem _ fem, 4 _ fire _ fyra, 0 _ null _ noll, 6 _ seks _ sex, 7 _ syv/sju _ sju, 9 _ ti _ tio, 2 _ to _ två, 3 _ tre _ tre;
Finite sequence with last and largest term a(992) = 8154067923.
From Charles Coker, Jul 18 2019: (Start)
The word tio (10) should probably be nio (9). Sources: 1) Wikipedia, List of numbers in various languages: Germanic languages, 2) Swedish Language Blog, Swedish numbers 1100.
The names are sorted using English sorting rules. In Swedish, the letter Å/å, like in åtta (8), comes after z. Alphabetical order is a, ..., z, å, ä, ö. Using Swedish sorting rules and nio for 9, the sequence for 09 would be 1, 5, 4, 9, 0, 6, 7, 3, 2, 8. Sources: 1) Swedish speaker (not me), 2) Wikipedia: Swedish alphabet.
