%N Numbers in decimal representation with distinct digits, such that in Norwegian and Swedish their digits are in alphabetic order.

%C 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;

%C Finite sequence with last and largest term a(992) = 8154067923.

%C From _Charles Coker_, Jul 18 2019: (Start)

%C 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 1-100.

%C 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 0-9 would be 1, 5, 4, 9, 0, 6, 7, 3, 2, 8. Sources: 1) Swedish speaker (not me), 2) Wikipedia: Swedish alphabet.
