Definition of Septenary
Septenary numbers are made up only of the digits \(\{0,1,2,3,4,5,6\}\). Each place in a septenary number corresponds to a power of \(7\).
Because there are only \(7\) different possible digits in a Septenary number, we also call them Base \(7\) numbers.
For example, the septenary number \(1206\) is equal to the decimal number \(1 \times 7^3 + 2 \times 7^2 + 0 \times 7^1 + 6 \times 7^0 = 343 + 2 \times 49 + 0 + 6 = 447\).
Some other examples of Septenary numbers are:
- \(66\), which corresponds to the decimal number \(48\).
- \(600\), which corresponds to the decimal number \(294\).
- \(101\), which corresponds to the decimal number \(50\).
