In number theory, the n-th cabtaxi number, typically denoted Cabtaxi(n), is defined as the smallest positive integer that can be written as the sum of two positive or negative or 0 cubes in n ways. [1] Such numbers exist for all n, which follows from the analogous result for taxicab numbers.
In mathematics, the nth taxicab number, typically denoted Ta(n) or Taxicab(n), is defined as the smallest integer that can be expressed as a sum of two positive integer cubes in n distinct ways. [1] The most famous taxicab number is 1729 = Ta(2) = 1 3 + 12 3 = 9 3 + 10 3, also known as the Hardy-Ramanujan number. [2] [3]
The taxicabs of the United States make up a mature system; most U.S. cities have a licensing scheme which restricts the number of taxicabs allowed. As of 2012 the total number of taxi cab drivers in the United States is 233,900; the average annual salary of a taxi cab driver is $22,820 and the expected percent job increase over the next 10 years is 16%.

Campus Area Bus Service (CABS) is a free public transportation system at the Ohio State University's Columbus campus. The system consists of five bus routes that connect various points of Ohio State's campus, and the immediate off-campus area. The system connects with the Central Ohio Transit Authority's bus routes at several points. [4]
In number theory, the generalized taxicab number Taxicab(k, j, n) is the smallest number — if it exists — that can be expressed as the sum of j numbers to the k th positive power in n different ways. For k = 3 and j = 2, they coincide with taxicab number.
In 1992, Ohio began using a numerical county-coding scheme to indicate the county of registration. The scheme assigns a two-digit number to each of the state's 88 counties in alphabetical order, beginning with 01 for Adams County and ending with 88 for Wyandot County. The scheme has been used on specialty plates since its introduction, and was ...
