A characterization of designs related to dodecads in the witt system S(5, 8, 24)

Vladimir D Tonchev
1986 Journal of combinatorial theory. Series A  
We prove that the .5- (24, 12, 48) design formed by the dodecades in the extended binary Golay code, as well as all l-designs (f > 2) obtained from it by derivation, are the unique designs with the given  ...  parameters and such that the cardinality of the intersection of any two blocks has the same parity (mod 2) as the block size.  ...  The same method was applied in [ll, 123 for a similar characterization of designs obtained by derivation from the Witt system S(5, 8, 24).  ...

CODING THEORY AND ALGEBRAIC COMBINATORICS [chapter]

MICHAEL HUBER
2010 Series on Coding Theory and Cryptology  
In particular, special interest is devoted to the relationship between codes and combinatorial designs. We describe and recapitulate important results in the development of the state of the art.  ...  This chapter introduces and elaborates on the fruitful interplay of coding theory and algebraic combinatorics, with most of the focus on the interaction of codes with combinatorial designs, finite geometries  ...  Solutions: ad (1): By Lemma 1.2 (b), we have to calculate b = 8·7·6 4·3·2 = 14 in the case of the Steiner quadruple system SQS(8), and b = 24·23·22·21·20 8·7·6·5·4 = 759 in the case of the Mathieu-Witt  ...

Medial catalexis in Sir Thomas Wyatt's iambic pentameter

Patrik Bye
2021 Nordlyd: Tromsø University Working Papers on Language & Linguistics  
The final part of the paper offers some speculations as to the nature of medial catalexis and how it can be approached within a linguistically informed framework compatible with generative metrics.  ...  There is a reasonable scholarly consensus that the long ("heroic") line of Sir Thomas Wyatt is an iambic pentameter.  ...  GP 502 In (55), the stressed syllables of both gold and iren align to a E (=S) position.  ...

Problem 15. 5 . 5 Determine when there exists a universal family on the full family of moduli spaces M (X/S) × S X.  ...  In our situation, the dodecad P can be degenerated on X to a configuration of 11 points on a rational normal cubic, plus a twelfth point in general position.  ...
