Properties

Appears in sequences

• Define an increasing sequence as follows. Given the first term, called the seed (which need not share the property of the remaining terms), subsequent terms are obtained by inserting at least one digit in the previous term so as to obtain the smallest number with the specified property. This is the prime sequence with the seed a(1) = 2.at n=6A068167
• a(1) = 1; for n > 1, a(n) is the smallest unused prime number that can be created by either removing or adding a single digit anywhere in the value of a(n-1).at n=19A389824
