011110110011001110101


The formula

d + p + 1 <= 2^p

(where d is the number of data bits and p is the number of check bits)

indicates that we need at least 5 check bits in order to correct single-bit errors in blocks of 16 data bits -- a (21,16) code.

SECDED requires 6 check bits for blocks of 16 data bits.
