Dear all,
I am looking to detect palindromes (sentence or number or other
sequence of units that can be read the same way in either direction)
and repeats (sequences of letters or numbers

which are repeating atleast twice within a string) in some strings
containing between 20-5000 letters. Has somebody any idea how could I
perform that using an Excel macro? I

would like that the string to be evaluated could be on cell "A1" and
that the detected palindromes and repeats could be listed bellow A2
and C2, respectively; and that the number

of times that they appear in the sentence could be listed bellow cells
B2 and D2, respectively, as the following small example:

QGAGGAAGGAGQ
Palindromes * * Number * * * * *Repeats * * * * Number
QGAGGAAGGAGQ * *1 * * * * * * * GA * * * * * * *3
GAG * * * * * * 2 * * * * * * * AG * * * * * * *3
GG * * * * * * *2 * * * * * * * GAG * * * * * * 2
AA * * * * * * *1 * * * * * * * AA * * * * * * *1
* * * * * * * * * * * * * * * * GG * * * * * * *2

Somebody could help me?
Thanks in advance,
Luciano

Correction:

QGAGGAAGGAGQ
Palindromes * * Number * * * * *Repeats * * * * Number
QGAGGAAGGAGQ * *1 * * * * * * * GA * * * * * * *3
GGAAGG * * * * *1 * * * * * * * GG * * * * * * *2
GAAG * * * * * *1 * * * * * * * AG * * * * * * *3
GAG * * * * * * 2 * * * * * * * GAG * * * * * * 2
GG * * * * * * *2
AA * * * * * * *1
