`83`

is the "sum of three consecutive primes (`23 + 29 + 31`

) as well as the sum of five consecutive primes (`11 + 13 + 17 + 19 + 23`

)."There is an AZ Hwy-83, which intersects with AZ Hwy-82. AZ Hwy-83 connects with Interstate 10 near Vail south to Parker Canyon Lake.

This nBAB about the number

`was updated with the following MathBabbler Number Analyst output as a result of creating a nBAB for the number 62. While working on the nBAB for 62, MathBabbler learned that Sigmund Freud had an obsession with the numbers 61 and 62 thinking they might be his death age. Freud was wrong and he ended up dying in 1939 at the age of`
