Problem 17.- The largest known sequence of consecutive and reversible primes.

I found last year (August 3, 1998) the following sequence:

{1193,1201,1213,1217,1223,1229,1231,1237,1249,1259}

(See  the Sloane’s sequence A040104, and see also my Puzzle No. 20 )

All of the ten (10) members of this sequence are consecutive primes and also reversible (non-palindromic) primes; this last means that 1193 and 3911 are primes, 1201 and 1021 are primes, and so on.

As far as I know this is the largest known sequence of this type.

Questions:
a) Can you find a larger sequence of this type?
b) Can you find a larger sequence including palprimes, if necessary?

Felice Russo has obtained (May 21, 1999) another sequence of 10 consecutive reversible non palindromic primes, 8 digits each:

{91528739, 91528777, 91528807, 91528817, 91528819, 91528823
91528837, 91528841, 91528903, 91528939}

Jud McCranie sent (May 22, 1999) one more 10 members sequence of consecutive reversible and non palindromic primes, 9 digits each, starting in 302706311 and ending in 302706493.

My feeling (CR) now - after this other two10 members sequences - is that an eleven members sequence of this type must exists...

Jud McCranie has gotten - at last, 27/05/99 - a sequence of 11 terms: 1477271183 through 1477271387.

Previously he got another sequences of 10 terms:
777528457-617
778286917-7109
924408493-619
and 1177842077 through 1177842269
***
One day after (28/05/99) he got another larger sequence (12 terms):
form
9387802769 to 9387803033.

Other results from him are:
Terms - From - To:
10 - 1801280717 - 1801280867
10 - 1811906567 - 1811906743
10 - 7060718569 - 7060718747
10 - 9338212141 - 9338212381
11 - 9427522387 - 9427522387

I extended the search range of Problem 17
(consecutive emirps) to 10^14 (plus a little bit)
and so I found  5 runs of length 13.
There is a large gap between the first run of length 12 (which starts at 9387802769) and the first run of length 13.

The primes (and their reverses) for the first sequence of length 13, which starts at 15423094826093, are:

1 15423094826093 39062849032451
2 15423094826147 74162849032451
3 15423094826149 94162849032451
4 15423094826197 79162849032451
5 15423094826213 31262849032451
6 15423094826257 75262849032451
7 15423094826267 76262849032451
8 15423094826287 78262849032451
9 15423094826339 93362849032451
10 15423094826341 14362849032451
11 15423094826351 15362849032451
12 15423094826369 96362849032451
13 15423094826389 98362849032451

The other such sequences of 13 terms
that  I found are:
16624937940797 - 16624937941187
78862056635899 - 78862056636373
99994515721939 - 99994515722411
100352695899791 - 100352695900157
